MILK-COOLER.

SPECIFICATION formingpart of Letters Patent No. 599,644, dated February22, 1898.

Application filed August 23, 1897.

To all whom it may concern:

Be it known that I, SIMEoN SNIDER, of Palatine, in the county of Cookand State of Illinois, have invented a new and Improved Milk-Cooler, ofwhich the following is a full, clear, and exact description.

My invention relates to an improvement in devices for cooling liquids,with a special reference to its use in connection with cooling milk andcream, although the device is applicable to the cooling of any liquid.

Reference is to be had to the accompanying drawings, forming'a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a top plan view of my device. Fig. 2 is a cross-sectionalelevation on the line 2 2 in Fig. 1, and Fig. 3 is a cross-sectionalelevation on the line 3 3 in Fig. 2.

My device is used in connection with a flowing stream of water or otherliquid, which is made to absorb and carry away heat from the liquid tobe cooled. It comprises a tank A, made of any suitable size and shape,within which the liquid to be cooled is placed. In the device as hereinshown and described this liquid will ordinarily be referred to as milkor cream,although the device may be used for cooling any other liquid.The two opposite'ends of the tank are provided with section of pipe BThis pipe immediately inside the edge of the tank is bent downward,

bers B and the'horizontal members B A The vertical portions 13' are ofsuch a length that the horizontal member B reaches substantially to thebottom of the tank when the pipe is oscillated. At one end of the pipe avertical nipple or short section is attached to one of the horizontalpivot-sections B and a hose A is connected thereto for supplying thewater or other cooling fluid- To the other end of the pipe is connecteda counterbalancearm 0, provided with a weight 0, attachable thereon atany point desired. The arm 0 extends in substantially the same directionas the members B of the pipe. WVhen the swinging portion of the pipe isthrown to one side of the center, the weight G will maintain theswinging portion of the pipe upon that side until power is appliedthereto to shift it.

- by brackets attached to boxes E on the tank A, and have buckets Eattached to their other ends. 4

The buckets E are made to slide in the boxes E or in any suitableguideway and are provided with ball-valves e in the bottoms thereof,said valves being retained in place by wickets or gratings e. Each valveis at: tached to a cord (2 whichat its upper end is attached to a pin 6at the top of the box E, the cord being of such a length that when thebucket has descended to a certain point the valve will be raised fromthe bottom of the bucket andthe further descent of the bucket stopped.Each bucket E is provided with a .bail E to which the cord G, connectingit with the counterweight-arm C, is attached. To the bail are alsoattached cords F, which extend over guide-pulleys f, supported bybrackets attached to the boxes E, and are connected at their upper endswith a bar F,pivoted to the free ends of the valve-levers d.

The pivot-sections B of the pipe through which the water flows from thetank are connected to a pipe D, which extends in opposite directionsfrom the section B and is provided at the sides of its connection with apipe with valves (1 and 61. These valves are connected to the levers din such a manner that when the levers d are held in one position thevalve 61 is opened and the valve d is closed, and when the levers d arethrown in the opposite direction, through the movements of theconnecting-bar F, the valve 01 will be closed and the valve d will beopened. The continuations D of the discharge-pipe are curved around, soas to discharge into one or the other of the buckets E.

The position of the parts as shown in Figs. 1 and 2 is with thehorizontal section B of the cooling-pipe to the left. In this positionthe bucket E upon the left side of the tank is raised and the valve 61is open. The water flowing through the cooling-pipe will thus bedischarged into the bucket E upon the left side of the tank. At the sametime the bucket E upon the opposite side of the tank and'in itslowermost position has the valve 6 opened and is therefore empty ofwater; As

soon as the water in the bucket which is up becomes heavy enough toovercome the counterbalance-Wight C the bucket will descend and pull thearm 0 over to the position shown in dotted lines in Fig. 2.

The bucket in its descent will stop when the cord 6 attached to theball-valve e, is tightened. This will raise the valve and permit thewater to flowout. As the bucket descends the cord F acts upon the bar F,connecting the valve-levers,and shifts the valves, so that the water isdischarged into the opposite bucket, which has been raised. Thisoperation will continue automatically and will result in swinging thehorizontal portion B of the cooling-pipe from one side of the tank A tothe other. This will result in stirring the contents of the tank and inshifting the cooling-pipe from one position to the other, thusfacilitating the rapid cooling of the contents of the tank.

In the drawings the swinging portion of the pipe is shown as consistingof a single pipe. Instead of this construction, however, a coil of pipeor a fiat receptacle may be used. The exact shape of this portion of thedevice is not material, the only point in this construction being tofurnish a suflicient amount of surface to secure rapid cooling and alsoto stir the contents of the tank.

This device is simple in its construction and certain in its operation.It will continue automatically to operate as long as the supply ofcooling-water is obtained. The water may be cooled artificially, ifdesired, or if more rapid cooling is desired than can be obtained by theuse of water any cooling fluid desired may be substituted therefor. Thiscooling fluid cannot injure milk, because it does not come in directcontact with it, and there is no possibility of its getting into it.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.
